"Andrés Muñoz-Jaramillo of Southwest Research Institute and José Manuel Vaquero of the University of Extremadura have developed a new technique for looking at historic solar data to distinguish trustworthy observations from those that should be used with care. This work is critical to understanding the Sun's past and future as well as whether solar activity plays a role in climate change.

"Scientists have been monitoring solar activity since Galileo made the first drawings in 1612 by counting sunspots and groups of sunspots," said SwRI's Dr. Andrés Muñoz-Jaramillo, a senior research scientist who is first author of a paper in Nature Astronomy outlining the research. "However, putting all observations in perspective is quite challenging due to wide-ranging observation techniques and telescope magnifications used. We see much more now and our understanding of what we see changes the way we count spots.""

Water discovered on Bennu!

"From August through early December, the OSIRIS-REx spacecraft aimed three of its science instruments toward Bennu and began making the mission's first observations of the asteroid. During this period, the spacecraft traveled the last 1.4 million miles (2.2 million km) of its outbound journey to arrive at a spot 12 miles (19 km) from Bennu on Dec. 3. The science obtained from these initial observations confirmed many of the mission team's ground-based observations of Bennu and revealed several new surprises."

"A team led by Southwest Research Institute has concluded that the surface of dwarf planet Ceres is rich in organic matter. Data from NASA's Dawn spacecraft indicate that Ceres's surface may contain several times the concentration of carbon than is present in the most carbon-rich, primitive meteorites found on Earth.

"Ceres is like a chemical factory," said SwRI's Dr. Simone Marchi, a principal scientist who was the lead author of research published in Nature Astronomy today. "Among inner solar system bodies, Ceres' has a unique mineralogy, which appears to contain up to 20 percent carbon by mass in its near surface. Our analysis shows that carbon-rich compounds are intimately mixed with products of rock-water interactions, such as clays."

"Astronomers have conducted spectroscopic observations of the cataclysmic variable ES Ceti, which resulted in uncovering important insights about gas emission from this object. The new findings, presented in a paper published November 29 on the arXiv pre-print server, suggest the presence of an accretion disk in this system."

"Several teams of researchers have announced that the skeletal remains of a hominin believed to have lived approximately 3.67 million years ago represent a new species of early human. The researchers report that the specimen, known as "Little Foot," has characteristics that make it unlike any other known species.

"China launched a rover early Saturday destined to land on the far side of the moon, a global first that would boost Beijing's ambitions to become a space superpower, state media said.

The Chang'e-4 lunar probe mission—named after the moon goddess in Chinese mythology—launched on a Long March 3B rocket from the southwestern Xichang launch centre at 2:23 am (1823 GMT), according to the official Xinhua news agency.

The blast-off marked the start of a long journey to the far side of the moon for the Chang'e-4 mission, expected to land around the New Year to carry out experiments and survey the untrodden terrain."
